THE SLAUGHTER OF THE VAMPIRES

In 19th Century Austria, a newlywed couple, Marquis Wolfgang (Walter Brandi) and Louise (Graziella Granata), acquire a castle. To commemorate the occasion, Louise performs a piano piece she has written during a party. Louise then feels a strange sensation and retires to her room. She is visited by a vampire (Dieter Eppler) who she originally sees at the party she was in and sucks her blood, leading her to desire him. As a result, Louise's health declines, leading to Wolfgang seeking aid from Dr. Nietzsche (Luigi Batzella). Wolfgang is too late as when the doctor arrives, Louise is already dead. As the doctor diagnoses this, Wolfgang is shocked to find Louise alive as she approaches him and sucks his blood. The doctor later seeks out Louise's hiding place and stakes her to death, along with the servant Corrine, also a vampire. Wolfgang's hiding spot is not found as the doctor seeks another abode in the castle. Wolfgang, not entirely converted into a vampire, corners his adversary and stakes him with spikes of an iron grating.

The doctor stakes Louise and Corrine to death after they become vampires, and Wolfgang defeats the main vampire adversary with spikes from an iron grating.

The climax delivers a classic vampire eradication sequence: both the transformed women and the central vampire threat are dispatched with traditional means, restoring order to the castle. The use of staking and iron grating reinforces gothic horror conventions, while the survival of Wolfgang, not fully converted, leaves a faint glimmer of ambiguity amid the otherwise definitive resolution.
